What to do after getting the first 5 ball materials?

I need to get the thing to suck up ball 7, the creature that sucks you in through air current

Well, first: do you have all 10 balls? If so, continue reading. If not, go find the others. Now, once you have them: go to the top of the mountain, the far right save (still on the top of the mountain). You need to go left from there with ball 7, and jump over the lava there, then go down, heading to the screen before crystal path. Being careful, jump over the lava in THAT screen now, and you should be in the screen before crystal path. Now, head right, being careful not to fall down that first shaft. I'll leave the rest to you to figure out (it should be exceedingly obvious from there, in fact, I believe I already told you)!

you need to go to lunar cheese extraction facility, on the western side of pinewood heights go ball 4 up>up, then go to save, switch to ball 6, go down, to that platform with that guy who gave you ball 6 as an image in the wall, go to that thing on the left and voila!

in the eastern side of pinewood heights, go left>down>right>down with ball 8. go through shadowlands and you have ball 9!

Go to time machine with ball 9, go all the way to the lake, go through, teleport to present and you have ball 0! hooray!
